Description

Technical Field

[0001] The invention relates to the technical field of roasting devices, and in particular to a low-temperature oxidation roasting device for high-titanium pellets. Background Art

[0002] Oxidized pellets are one of the important methods for making powder ore agglomerates. A roasting device is used for roasting oxidized pellets. The roasting device generally includes a roasting furnace and a feeding mechanism for conveying green pellets. However, the feeding mechanism for conveying green pellets in the existing roasting device has a single function and does not have the function of pre-heating and drying the green pellets during the feeding process, which causes the surface of the green pellets to crack due to a sudden rise in temperature. In addition, the mineral powder adhered to the surface of the green pellets will not be processed, which will lead to poor surface smoothness of the oxidized pellets.

[0003] In order to solve the above technical problems, the existing patent document with announcement number (CN218146875U) discloses a roasting device for the production of titanium oxide pellets, including a roasting furnace body, a conveying platform, a fan, an electric heating network, a dust suction pipe and a dust suction equipment host and other components. The hot air generated by the fan and the electric heating network is used to pre-dry the raw pellets laid and conveyed on the raw pellet conveying platform, which can adapt to the high water content when producing raw pellets in winter. The use of hot air to pre-dry the raw pellets can increase the temperature of the surface of the raw pellets, improve the heating efficiency during roasting, and reduce the trouble of cracking of the surface of the raw pellets caused by a sudden rise in the temperature of the raw pellets. The dust suction pipe uses the suction force generated by the operation of the dust suction equipment host to adsorb dust on the surface of the raw pellets, which is beneficial to improving the product quality of the oxidized pellets. Finally, the raw pellets are sent to the oxidizing atmosphere of the roasting furnace body for roasting, so that the raw balls are agglomerated to form pellet ore.

[0004] However, in the above-mentioned prior art, the bottom surface of the green pellets is less heated because it is in contact with the conveying platform, which leads to uneven preheating of the green pellets and affects the product quality of the pellets. Summary of the invention

[0005] The purpose of the present invention is to provide a low-temperature oxidation roasting device for high-titanium pellets, aiming to solve the technical problem in the prior art that the bottom surface of the green pellets is less heated due to contact with the conveyor table, resulting in uneven preheating of the green pellets and affecting the product quality of the pellets.
